Across the globe, as mining and oil firms race for dwindling resources, indigenous peoples are battling to defend their lands - often paying the ultimate price. It has been called the world's second oil war", but the only similarity between Iraq and events in the jungles of northern Peru over the last few weeks has been the mismatch of force. On one side have been the police armed with automatic weapons, teargas, helicopter gunships and armoured cars. On the other are several thousand Awajun and Wambis Indians, many of them in war paint and armed with bows and arrows and spears. The Indians this week warned Latin America what could happen if companies are given free access to the Amazonian forests to exploit an estimated 6bn barrels of oil and take as much timber they like. After months of peaceful protests, the police were ordered to use force to remove a road block near Bagua Grande. In the fights that followed, at least 50 Indians and nine police officers were killed, with hundreds more wounded or arrested. The indigenous rights group Survival International described it as "Peru's Tiananmen Square". "For thousands of years, we've run the Amazon forests," said Servando Puerta, one of the protest leaders. "This is genocide. They're killing us for defending our lives, our sovereignty, human dignity." Peru is just one of many countries now in open conflict with its indigenous people over natural resources. Barely reported in the international press, there have been major protests around mines, oil, logging and mineral exploitation in Africa, Latin America, Asia and North America. Hydro electric dams, biofuel plantations as well as coal, copper, gold and bauxite mines are all at the centre of major land rights disputes.
